And then that led us to discussing about water density and why you feel lighter swimming in the sea than in a chlorinated pool .

And I thought. What a perfect time to do this experiment.

And we did.

I think that density is not the easiest thing to teach. When explaining to little kids, some people sometimes just explain it as weight — which is not really the complete picture. But then if you start explaining more, it could get too complicated, right?

But anyway, if you’re looking for an easier way to teach density, you might find the videos at the bottom of this page helpful.

Density Experiment With Water Instructions

First, pour water into the two glasses until about an inch from the top.

Next, put 3 tablespoons of salt in one of the glasses.

Then stir it well to dissolve the salt properly.

Afterwards, put the egg in the first glass. Like any fresh egg, it sinks to the bottom of the glass

Next, try and put that same egg in the salt solution.

The egg floats! This is because the water with salt is now more densed than the egg. And so, the egg is now less dense making it float to the top.

This Experiment On Video

And here are a couple videos that can help kids grasp the concept of density. You may need to turn up the volume with the second video but it is one of the best videos I’ve found that explains density very clearly.
